In 1990, the Cookie Crook was given a sidekick named Chip the Dog. Chip would howl the cereal's name ("Coo-oooooooooookie Crisp!") in each ad before he and his master were inevitably foiled by the Cookie Cop.
After General Mills bought the Cookie Crisp trademark Chip the Dog continued to be the mascot with the Cookie Crook and Cookie Cop from 1997 to 2005. In the format of the advertisements, Chip was a friendly pooch, no longer wearing a mask, who offered Cookie Crisp to a group of kids. Typically an adult would interfere on the grounds that cookies are not breakfast food. Near the end of the ads, the adults would change their minds once Chip gave them a taste of his Cookie Crisp.
